| In conclusion, we propose the following nomenclatural alterations. For a good classification, the genus Vulpia is to be accepted as a member of the Festuceae. Various names of Vulpia are fixed according to our present rules of nomenclature, viz. V. bromoides (L.) GRAY, V. membranacea (L.) LINK, V. geniculata (L.) LINK, V. stipoides (L.) DUM. and V. Myurus (L.) GMELIN. For Vulpia ciliata the earliest valid epithet is taken and so this widely distributed species must bear the name of V. aetnensis TINEO, while its glabrous variety is named imberbis (Vis.) HENR.. Vulpia delicatula (LAG.) DUM. var. hirsuta HENR. and Vulpia geniculata (L.) LINK var. dasyantha HENR. are described as new varieties. Among the South American species the new combinations Vulpia... |

| Examining the material of the genus Charybdis de Haan in the RijksMuseum van Natuurlijke Historie and in the De Man-collection in the Zoological Museum at Amsterdam for comparison with material of the Siboga expedition and other expeditions for Prof. Dr Max Weber and the Zoological Museum at Amsterdam, I made the following notes. I am very much indebted to Prof. Dr H. Boschma for his kindness in placing his material at my disposal and for his hospitality at the Leiden Museum. Charybdis (Goniosoma) merguiensis (De Man) Goniosoma merguiense, De Man, 1888, Journ. Linn. Soc. Zool., vol. 22, p. 82, pl. 5 figs. 3 & 4;1895, Zool. Jahrb. Syst., vol. 8, p. 560. Charybdis (Goniosoma) merguiensis, Alcock, 1899, Journ. As. Soc. Bengal, vol. 68 pt. 2, p. 56;... |

| Much of the difficulty experienced by the modern systematic botanist is nomenclatorial. Though he may have a clear conception of a plant as a taxonomic unit, he is often at a loss to find out what it is as a legitimate nomenclatural entity. If a haphazard use of names is permitted, it will result in different botanists using the same name in a different sense, so that the names themselves, unaccompanied by a description, will give no definite denotation; that is, a name may become applicable to several independent taxonomic units. And if it is attempted to skip over these difficulties by creating a new name every time the legitimacy of a name of a plant is questioned, a usage may be established in virtue of which, on the one hand, very good names may be... |

| Dysdercus mendesi nov. spec. Dysdercus spp. 1936, Mendes, L.O.T., Boletim Technico N. 23, Institute Agronomico de Campinas, II, Os "Manchadores" do Algodao, p. 4 pl. I—II. This species is rather similar to D. columbicus m. and to D. brevis m.; the whitish annulation to the ultimate antennal joint is usually indistinct, the pronotum shows no black transverse stripe behind. The third joint of the tarsi, however, is not lighter than the second, the general form is more elongate, the pronotum less broad, the antennae are slightly longer and the membrane is darker, especially at the base. The structure of the male genital segment differs from that of D. columbicus in showing a less pronounced inflexion in the apical edge, the protuberant parts less angular, the... |

| In this paper a series of experiments is described relating to the deformation of the earth's crust by horizontal compressive stress. A floating model crust is compressed in most cases, after a slight dent has been run across it to represent a geosyncline. When materials of the correct order of strength are used, the crust buckles down below the model geosyncline forming a root at the lower surface of the crust. At no time in this process is a topographic depression formed at the surface that exceeds the depth of deep-sea troughs as compared to the thickness of the earth's crust. Other possibilities suggested by the experiments are that the crust may break through and overthrust and that a broad geosyncline will surmount a more complicated form of root. It... |

| Den Anlass zu der vorliegenden Arbeit bildete eine Sammlung neogener und quartärer Echiniden, welche von Herrn Dr. J. Cosijn bei Modjokerto (Java) gesammelt wurden und mit deren Bearbeitung mich im Frühjahr 1932 Herr Dr. I. M. van der Vlerk, Konservator am „Rijksmuseum van Geologie en Mineralogie” zu Leiden, beauftragte. Diese Sammlung wurde schon bald Anlass zu einer Revision der in Leiden befindlichen fossilen Echiniden des Indischen Archipels. Ausserdem erwies es sich als wünschenswert, auch die Echiniden der Selenka-Trinil-Expedition aus dem Geologisch-Palaeontologischen Museum der Universität Berlin einer Neubearbeitung zu unterziehen. Herrn Prof. Dr. W. Janensch möchte ich an dieser Stelle meinen verbindlichsten Dank aussprechen für das Ausleihen und... |

| Among the old plant collections in book-form, in the Leyden National Herbarium, there are two large volumes, containing a number of well preserved Ceylon plants. These plants are said to have been collected by PAUL HERMANN in the latter half of the 17th century. PAUL HERMANN¹), afterwards Professor of Botany at the University of Leyden, resided in Ceylon as an ”Ordinary and First Physician“ of the Dutch East Indian Company during the years 1672—1679. Several particularities on his life and on the collections made by him, are to be found in LINNAEUS’S Flora Zeylanica (6), in TRIMEN’S paper entitled ”Hermann’s Ceylon Herbarium and Linnaeus’s Flora Zeylanica“ (8), in BOULGER’S study on the history of Ceylon botany (2) and in ARDAGH’S note on HERMANN’S... |

| Egg-capsules of the following four Raja-species have been known with certainty for many years from the shores of the Netherlands: Raja clavata Linnaeus, Raja montagui Fowler (Raja maculata Montagu), Raja radiata Donovan, and Raja batis Linnaeus. It is therefore of interest to note that from 1931 to 1935 and in 1936 egg-capsules diverging strongly from the well-known species, have been found on the beach between Wassenaar and Noordwijk (in the province of South-Holland). These capsules appeared to belong to the following five species: Raja brachyura Lafont, Raja naevus Müller and Henle, Raja undulata Lacépède, Raja microcellata Montagu, and Raja marginata Lacépède. The determinations have been made with Clark's (1922) paper, with the exception of Raja... |

| I have hesitated some time over the title of the present paper. The alternative was something like: ”WALLACE versus ZOLLINGER“ or ”The ”idea of a demarcation line through Malaysia, a limiting factor towards ”the progress of biogeography“. However, the first being too agressive, and the second too melodramatic ,the one found in the heading was chosen. The above introductory lines mean to put the reader at once face to face with the nucleus of what I will discuss here: the question how ZOLLINGER’S ”Karte der Flora Malesiana“ of 1857 was apparently almost entirely forgotten, although it well deserves to come under the eyes of modern biogeographers, for the sake of the honour of its author and of the priority of his work. |

| The present catalogue of the Doliidae has been composed in the same way as my former catalogues. I have entered in it, not only the Doliumspecies present in the collections of the Rijksmuseum van Natuurlijke Historie, but also all the other species that I found mentioned in literature of which we have no material. In Lamarck's time (1822) only 7 Doliums were known, while Reeve in 1849 described 15, which number has since grown to approximately 54 species or varieties. Of all these species I give the principal synonyms and after those of which we possess material, follows a list of the specimens, stating 1) the letter under which it is entered and in the case of material on spirit the number of the bottle, 2) the number of specimens, 3) the locality; if... |

| I have already published in the Malayan Orchid Review, 1936, pp. 104—109, a brief account of two artificial hybrids in the genera Arachnis and Renanthera, and since then have had flowers of a third for examination. The account already written is of a semipopular nature, intended chiefly for orchid-growers, and a more detailed description with some remarks on the botanical aspects of the question appear to be worth publishing. The three hybrids concerned are Arachnis flosaeris X A. Hookeriana, Arachnis Hookeriana X Renanthera coccinea and Arachnis Hookeriana X Renanthera Storiei. All three were raised at the Botanic Gardens, Singapore. The first is of interest because the hybrid is practically identical with Arachnis Maingayi, which has been described as a... |

| The bulbils of Dioscorea sansibarensis fall at maturity and are carried away from the parent plant, if at all, by water: they rest through the Dry season; and germinate when the soil under them is able to supply moisture. The new plant, is thrust into the surface of the soil and there shaped by its geotropic responsiveness. Its tuber is the result of a more or less one-sided enlargement of the first internode of the axis: it is perennial and its greatest growth becomes annular. The annual stems, which rise from the tuber are produced cymosely, each from the lowest axil of its parent axis; and, by arrest of internodes between them, all are sessile on the tuber. Thus crowded they are unable to grow in positions which are theirs theoretically and are... |
